Quantitative constraints on the timing and temperatures associated with Quaternary fault slip inform earthquake mechanics and seismic hazard analyses. Optically stimulated luminesce (OSL) and thermoluminescence (TL) are tools that can provide these constraints from fault gouge and localized slip surfaces.

The results of synchronous detection of the emission of various components of the electromagnetic and acoustic fields obtained under conditions of low industrial interference and a high level of microseismicity are investigated. To compensate electromagnetic radiation of lithospheric origin, a compensation method was used.

The paper aims to detail the procedure of selecting and scaling recorded seismic accelerations according to requirements specified by TCVN-9386:2012. The target response spectrum and the fundamental vibration period of the considered structure are critical factors for the selecting and scaling process.

Analysis of ca. 1400 km of multichannel seismic data indicate that the distal part of the Sakarya Canyon within the continental rise is an unstable region with sediment erosion. Fourteen buried debris flows (DB1–DB14), in the stacked form within Plio–Quaternary sediments between 1400 and 1950 m water depth, were observed in the surveyed area. Their run-out distances range from 3.8 to 24.4 km. The largest debris flow DB10 affects ca. 225 km2 surficial area transporting ca. 15 km3 of sediment in S to N direction.

On October 30, 2020, a strong earthquake (Mw6.6–7.0) occurred offshore, just north of Samos Island, causing life losses, injuries and damages, especially on the Turkish side. The broader area is characterized by a complex geodynamic setting with both rich seismic history and numerous active faults of different direction and kinematics. The first aim of this study is to define the seismic source of the mainshock, based on seismological and geodetic data (GPS measurements and originally processed GNSS records), as well as our field observations on Samos Island few days after the mainshock.

The average QES value is consistent with the previous results obtained in some back-arc regions such as Japan Sea and may suggest a similar termination age of spreading process. However, since the distribution of 90 ray paths can be roughly classified into two directions, northeast-southwest (NE-SW) and northwest-southeast (NW-SE), the average Q values of these two directions are derived to be QNE-SW = 455±109 and QNW-SE = 133±50, respectively.

This acoustic imaging has identified a canyon system at the slope and a shallow marine fan, which contains shelf incisions extending the İstanbul Strait incision. Multibeam bathymetry, ultra-high resolution seismic profiling and coring correlations on this subaqueous fan area allowed reconstruction of morphology and patterns of sediment distribution indicative of high energy sediment transport processes.

The paper focuses on the shaking test program, including materials, similitude law and scaled model, instruments, seismic waves and loading program. Consequently, a comprehensive understanding on the process of shake table test is revealed thanks to the results of an investigation on a precast frame structure made of recycled aggregate concrete.

This article presents a new design of earthquake instrumentation that is suitable for quick decisionmaking after the seismic event at the nuclear power plant (NPP). The main objective of this work is to ensure more availability of the NPP by expediting walk-down period when the seismic wave is incident. In general, the decision-making to restart the NPP after the seismic event requires more than 1 month if an earthquake exceeds operating basis earthquake level.

In this paper, a model of earthquake forecast is presented to assess the long-term probabilities of future earthquakes with moderate magnitudes for a region including Iran (latitude 25-40° and longitude 44-62°). The model estimates a coupled rate of magnitude, space and time for future seismicity using a spatial-temporal Poisson process.

Subduction is a major process that plays a first-order role in the dynamics of the Earth. The sinking of cold lithosphere into the mantle is thought by many authors to be the most important source of energy for plates driving forces. It also deeply modifies the thermal and chemical structure of the mantle, producing arc volcanism and is responsible for the release of most of the seismic energy on Earth. There has been considerable achievements done during the past decades regarding the complex interactions between the various processes acting in subduction zones.

Oceanography is a very complex science. Its field study, the knowledge of the oceans and the seas and their physical and biological characteristics, is fundamental to comprehend many oceanographic and ecological aspects that directly influence the human life and the planet health. From micro-scale, like coastal processes, to macro-scale, like Global Change, the oceans, the seas and the marine life, play the main role to maintain the earth equilibrium, both from a physical and a chemical point of view (e.g. carbon cycle and water masses dynamic)....
